ているところである。(B) Conventional technology LEDs have extremely high reliability compared to incandescent light bulbs, and are therefore widely used in various fields including pilot lamps for various electronic devices. On the other hand, the emission colors of LEDs are roughly classified into three colors, red and green using Ga-based compound semiconductors such as GaP and GaAlAs, and blue using SiC. It is well known in principle that a full-color light emitting device is formed by combining these three colors.

全体としての発光効率の低下を来す。(C) Problems to be solved by the invention On the basis of such a principle, when resin pellets of three primary colors of red, green, and blue are integrally incorporated to perform full-color light emission, a resin molding method is used. If a transparent material is used as the resin in terms of luminous efficiency, the color of the primary color pellet itself can be directly seen, and color mixing cannot be performed well. On the other hand, it is desirable to use an opaque resin from the viewpoint of color mixing, but light is attenuated in the opaque resin, resulting in a decrease in overall luminous efficiency.

FIG. 2 shows a side view of the apparatus as seen through the inside,
(1) is a metal header on which red LED pellets (2), green LED pellets (3), and blue LED pellets (4) and (4) are arranged. It should be noted that only two blue LED pellets (4) and (4) are incorporated in other color LEs.
This is because the emission brightness thereof is lower than that of the D pellets (2) and (3). (5) (5) is each LED pellet (2) (3)
It is an external lead wire corresponding to (4). (6) is each LED arranged on the upper surface of the metal header (1)
(2) (3) (4) Light-transmitting first molding resin for integrally molding pellets, which is made of a transparent epoxy resin and has a diffusing effect on light when mixed with the transparent resin. About 20% by weight of SiO 2 powder is mixed.
(7) is a translucent second mold resin that integrally molds the header (1) and the external leads (5) and (5) including the first mold resin (6). made of the same transparent epoxy resin, about 1 of SiO 2 powder
It is mixed by weight%.

(3) Each LED pellet (2) (3) (4) is mixed by mixing 20% by weight of SiO 2 which is a light diffusing material into the first molding resin (6) which is directly contacted with (4) and is molded. Each color from each is well mixed, ie each pellet (2)
Single colors from (3) and (4) themselves are mixed in this first mold resin (6), and intermediate colors of the emission colors from the LED pellets (2), (3) and (4) of the respective colors are obtained.
For example, when the red LED and the blue LED are turned on, purple is colored, and by turning on the red LED and the green LED, yellow can be obtained. Then, by molding the outer periphery of the first mold resin (6) with the second mold resin (7) containing only a small amount of SiO 2 , the light mixed well by the first mold resin (6) is emitted. The LED pellets (2) (3) (4) are obtained from the outside atmosphere while obtaining the desired lens action and condensing light with almost no attenuation.
Etc. can be protected.

第２のモールド樹脂（７）にも僅かな光拡散材を混入す
るのが好ましいことが実験的に確かめられた。From the point of view of light attenuation, it is better not to mix a light diffusing material in the second molding resin (7). However, in order to make the mixed resin emit light of a mixed color, It was experimentally confirmed that it is preferable to mix a slight amount of the light diffusing material also in the molding resin (7).

LED装置に多大の便益をもたらす。(G) Effect of the Invention In the multicolor LED device of the present invention, the mixing amount of the light diffusing material in the first molding resin is an amount capable of obtaining an intermediate color of the light emission colors from a plurality of types of LED pellets, and Since the amount of the light diffusing material mixed in the second mold resin having a lens function is such that the light mixed in the first mold resin is hardly attenuated, the amount of light extracted to the outside is small. The light can be condensed in a good color mixture state, the color mixture emits light from the entire resin mold, and the LED pellets can be protected. Therefore, multicolor emission including full color
It brings great benefits to LED devices.
